No, but I don't think that's necessarily the point of a forever project nor of life in general. It's not a goal of mine nor of none of my friends who have one; most of the projects from people I know cannot even make money even if (partly) completed.

Edit: If you mean, you need money to live; you of course need some money, but not as much as most people think. Which makes it a question of priorities mostly. There are plenty of fantastic places where $600-700/mo will get you far, even without losing that much from your 'previous life'. You have to sacrifice things obviously, but not that much (depending on what you are used to).
